Abstract

A pressure flushing system for use in a toilet tank includes a housing with a water inlet conduit, an air and water inlet assembly connected to the conduit and to the housing, and a water outlet for the housing. There is a flush valve within the housing for controlling flow of water from the inlet to the housing outlet. The air and water inlet assembly includes a chamber, with a water inlet connected to the chamber, and an outlet connected to the chamber. There is an air inlet accessible to air at atmospheric pressure and a passage between the air inlet and the chamber. A check valve is located in the passage, with the check valve opening in response to a venturi effect caused by water flow through the chamber to draw air into the chamber to mix with water flowing through the chamber and to the outlet. The check valve includes an elastomeric sleeve positioned within the passage and having normally closed flexible lips extending toward the chamber. The lips open to permit the passage of air into the chamber to mix with the water therein when there is a pressure in the chamber less than atmospheric.
